Answer:
-9/11
Step-by-step explanation:
You have to find the reciprocal of the number you're dividing by. In your case the number you are dividing by is 11/6. Just flip 11/6 to get the reciprocal, and the multiply it by -3/2. 6/11 is the reciprocal of 11/6.
[tex]-\frac{3}{2} * \frac{6}{11} = -\frac{18}{22}[/tex]
Simplify by dividing by 2.
-9/11 is the answer.

Answer:
D is the answer
Step-by-step explanation:
The revenue for a company producing widgets is given by y = -10x2 - 25x + 125, where x is the price in dollars for each widget. The cost of the production is given by y = 60x - 10. Determine the price that will allow the production of the widget to break even.
When they create 3.44 products and make a revenue of $76.027, they will break even.
Step-by-step explanation:
To do this, simply graph the 2 equation in a graphing calculator and analyze the graph for where the 2 graphs intersect. Discard the negative intersection because we cannot have a negative production. You should see that your intersection point is (3.441, 76.027).
GENERATE THE FIRST 4 Terms of f(n)=-2(n-1)+8
Help
Answer:
8, 6, 4, 2
Step-by-step explanation:
f(n)=-2(n-1)+8
Plug n =1
f(1)=-2(1-1)+8 = - 2*0+8 = 0+ 8 = 8
Plug n =2
f(1)=-2(2-1)+8 = - 2*1+8 = - 2+ 8 = 6
Plug n =3
f(1)=-2(3-1)+8 = -2*2+8 = -4+ 8 = 4
Plug n =4
f(1)=-2(4-1)+8 = -2*3+8 = -6+ 8 = 2
The diagonals of this rhombus are 8 and 16 units long. Their intersection creates four right angles, two 4-unit-long segments, and two 8-unit long segments. Given this information, find the area of the rhombus in square units (Use only the digits 0 – 9 and the decimal point, if needed, to enter a number).
Answer:
[tex]64\ \text{sq. units}[/tex]
Step-by-step explanation:
Area of a rhombus is the product of the length of the diagonals divided by two.
Length of one diagonal is 8 units and the other diagonal is 16 units
Area is given by
[tex]A=\dfrac{8\times 16}{2}\\\Rightarrow A=64\ \text{sq. units}[/tex]
The area of the rhombus is [tex]64\ \text{sq. units}[/tex]
Another approach is the diagonals have created 4 triangles where the base and is height is either 4 units long or 8 units long so the area of the rhombus would be the area of the 4 triangles.
[tex]A=4\times \dfrac{1}{2}\times 4\times 8\\\Rightarrow A=64\ \text{sq. units}[/tex]

what is the integer of The change in a balloon's volume when it loses 450 cm3 of air.
Answer:
The integer change is -450 cm^3
Step-by-step explanation:
Here, we want to write the integer of the change in the volume of a ballon when it loses 450 cm^3 of air
Losing this volume means we are subtracting 450 from the original volume
This represents a change of -450 cm^3
The graph of y = |x − 3| + 2 is reflected across the x-axis and then translated down 2 units. What is an equation of the transformed graph?
Answer:
y=-|x − 3|
Work
y = |x − 3| + 2
-2 -2
y = |x − 3|
add a neg before the absolute value
y=-|x − 3|
Transformation involves changing the position of a graph
The equation of the transformed graph is [tex]\mathbf{y = -|x -3| - 4}[/tex]
The equation is given as:
[tex]\mathbf{y = |x -3| + 2}[/tex]
The rule of reflection across the x-axis is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{y = -|x -3| - 2}[/tex]
The rule of translation 2 units down is:
[tex]\mathbf{(x,y) \to (x,y-2)}[/tex]
So, we have:
[tex]\mathbf{y = -|x -3| - 2 - 2}[/tex]
[tex]\mathbf{y = -|x -3| - 4}[/tex]
Hence, the equation of the transformed graph is [tex]\mathbf{y = -|x -3| - 4}[/tex]

Evaluate the function: f (x)=4x-1. Find f (5)
Answer:
f(5)= 4(5)-1
=20-1
=21
The evaluated value of f(5) is 19, which is determined by performing the arithmetic operations.
The linear function is given as follows:
f(x) = 4x - 1
To evaluate the function f(x) = 4x - 1 and find f(5), we substitute x = 5 into the function.
f(5) = 4(5) - 1
= 20 - 1
= 19
Therefore, f(5) is equal to 19.
The function f(x) = 4x - 1 represents a linear equation. In this case, when x is equal to 5, the value of f(x) can be calculated by substituting x = 5 into the equation.
By performing the necessary arithmetic operations, we find that f(5) is 19.

what is the value of the expression of 83-5x6
Answer:
x = 77/5
Step-by-step explanation:
I am going to assume that the equation is 83 - 5x = 6. First, we need to subtract 6 on both sides. So, our equation should look like 77 - 5x = 0
Then, add 5x to both sides. So, the equation should be 77 = 5x. Divide by 5 on both sides to get x = 77/5.

if a scarf is 25 percent off and normally cost 20 dollars how much will it cost after 6.5 percent sales tax is paid?
Answer:
$15.98
Step-by-step explanation:
25% off means it is 75% of its normal cost
0.75 x 20 = 15
The scarf is $15 after 25% discount. Then we calculate its final cost after tax:
6.5% = 0.065
1.065 x 15 = 15.975 which rounds to $15.98
Answer: 15.98
Step-by-step explanation: 25% off 20 is 15. 6.5% times 15 is .98 so the answer is 15.98
